I have been incredibly delinquent in writing to my blog; I sincerely apologize to all (any of?) my loyal readers and promise that I will start to say all the wonderful things that I thought about blogging, but have not.

For the moment a quick, quick update: I was travelling a lot. Mexico -- Merida and the Yucatan; Mongolia -- where I gave a talk and now have a pad in Ulaan Baatar; China -- Beijing and Chengde; England -- Bristol, Salcome, London; Bermuda by sailboat and then on to St. Martin and St. Barths.
